  // Override draw function, by default it will be called 60 times per second
  processing.draw = function() {
    // determine center and max clock arm length
    var centerX = processing.width / 2, centerY = processing.height / 2;
    var maxArmLength = Math.min(centerX, centerY);

Functional Automatic Tests (with Selenium)
